Which concourse does my airline use at Atlanta?+

Concourses T, A, B, C: Delta domestic (the vast majority of ATL's traffic). Concourse D: all non-Delta US carriers — American, United, Alaska, Southwest, Spirit, JetBlue, Frontier, Hawaiian. Concourse E: Delta international + most foreign carriers (Air France, KLM, BA, Lufthansa, Korean Air, Aeroméxico, Qatar, Turkish, LATAM, Virgin Atlantic). Concourse F: newer wide-body international + some Delta long-haul.

How do I get from Atlanta Airport to downtown?+

MARTA Red or Gold rail line — $2.50, 15-20 min direct to Five Points station downtown. Best option, cheap + reliable. The station is integrated with the airport — follow signs after baggage claim. Taxi $30 flat to downtown zone. Uber $20-$50. Avoid driving in rush hour — I-85 traffic is brutal.

What is the Plane Train at Atlanta?+

A free underground automated rail line connecting all 7 concourses (T, A, B, C, D, E, F) under the airport. Runs every 2 minutes, 24/7. Each concourse stop has a unique audio jingle. The Plane Train is the only way between concourses — there's no walking shortcut. Allow 5-15 min for any concourse-to-concourse transfer including the walk to and from the train.

How long do I need for an Atlanta connection?+

Same concourse: 45-60 min domestic. Between concourses (Plane Train + walk): 60-90 min domestic. International arrival (E or F) → domestic departure: 2.5-3 hours after immigration + customs + bag re-check. Delta's minimum domestic-to-domestic published is 35 min same-terminal but very tight; allow 90 min in practice for the long walks.

How early should I arrive at ATL?+

Domestic: 2 hours. International: 3 hours. ATL's security is busy (3rd busiest TSA checkpoint in the US after JFK + LAX). Peak times (5-9am Monday and Friday departures): 45-90 min waits without PreCheck. PreCheck is essential at ATL — 5-15 min vs 45+ general. Clear works at ATL as well.

Is Atlanta really the world's busiest airport?+

Yes — ATL has been the world's busiest passenger airport in every year since 1998 (briefly displaced by PEK during 2020 COVID). 108M passengers in 2024. Why: Delta's mega-hub strategy (75%+ of flights) plus geographic position within 2 hours of 80% of the US population. Atlanta also has the most takeoffs and landings of any airport in the world.
